Clinical Staff

Laurie was born and raised in New City, N.Y. As a child, she spent a lot of time on her grandparents’ farm, and those are some of her favorite memories.

She has lived in Georgia for more than 30 years, so she’s a southerner at heart. She started out in early childhood education and taught elementary school for 23 years. After she finished raising her children, she decided to go back to school to fulfill her childhood dream of becoming a nurse. She has loved being a nurse in varied areas, including rehabilitation, medical-surgical, and oncology.

She has always been interested in health and nutrition, but after a close family member was diagnosed with cancer, her quest for a better way began. Eventually, she made the switch from traditional oncology to integrative oncology.

Laurie has three children and six grandchildren. She loves spending time with her grandchildren and has tried to re-create a mini-farm to build special memories with them. She has had chickens, rabbits, dogs, and cats, and still plans to have a piglet and a goat.

Mandy Rittenour, RN
Clinical Staff

Mandy is a native New Yorker, but considers herself a Floridian after moving to Florida with her family when she was just a teenager. Her grandmother was involved in the medical profession, so she grew up around hospitals. Mandy attended the University of Florida and graduated with a Bachelor of Science degree in Nursing. “Sorry Bulldog fans, I am a hardcore Gator,” says Mandy.

She moved to Georgia in 2019, and is adjusting to the colder weather. She finds the state absolutely
beautiful, and the people wonderful. Mandy and her husband moved to the area to be closer to their daughter, son-in-law, and granddaughter. They feel fortunate that they can be close by to share in all of her granddaughter’s milestones.

Mandy has been a nurse for nearly 40 years, and states that she has probably done everything except pediatrics. She started in critical care, then transitioned to the emergency room. She also has experience in marketing, home health, and nursing home administration. She has also overseen a heart catheterization lab, where stents and pacemakers were inserted.

More recently, Mandy decided to work in oncology after seeing firsthand the struggles two of her
friends endured when receiving their cancer diagnoses. She transferred to an outpatient oncology clinic operated by her local hospital in Florida, and fell in love with the patients as well as the work itself.

After moving to Georgia, Mandy discovered The Center for Advanced Medicine. She states, “I am thrilled to be part of the team here!”

In her spare time, Mandy spends every minute she can with her daughter and granddaughter. She also enjoys hot yoga, going for walks with her golden retrievers, and riding motorcycles with her husband to take in the gorgeous scenery.
